Lisa rented the same car for 3 days, drove it 350 miles, and spent $185. What is the charge per day and the charge per mile for the compact car?
6.) The length of a rectangle is equal to triple the width. Find the length and width of the rectangle if the perimeter is 86 centimeters.
7.) The Frosty Ice-Cream Shop sells sundaes for $2 and banana splits for $3. On a hot summer day, the shop sold 8 more sundaes than banana splits and made $156. Find the number of sundaes and banana splits that were sold that day.
8.) At a college bookstore, Carla purchased a math textbook and a novel that cost a total of $54, not including tax. If the price of the math textbook is $8 more than 3 times the price of the novel, find the price of each book.
9.) A travel agency offers different getaways to New York. Plan A includes hotel accommodations for 3-nights and 2-pairs of baseball tickets for $645. Plan B includes hotel accommodations for 5-nights and 4-pairs of baseball tickets for $1135. How much does a single hotel cost and how much does a single pair of baseball tickets cost?
